AISTATS and CMT are independent websites with separate user accounts. We request you use the same email address for each because it makes it easier for us to link accepted papers to AISTATS accounts.

I have two different virtual.AISTATS.org accounts, can you merge them?
I have two different AISTATS accounts,
Can you merge them?
Each virtual.AISTATS.org has only one email address. Many people have multiple email addresses and as a result the can end up with multiple virtual.AISTATS.org accounts.
A common situation is that you submitted a paper on OpenReview/CMT with an email that is different than your virtual.AISTATS.org account email. When we import accepted papers we create accounts for authors who do not have an account with the email that they used on OpenReview/CMT. virtual.AISTATS.org, CMT and OpenReview are all separate systems so the only way we have of linking accounts between them is by email address
We recommend that you merge your accounts so that all you registrations and papers are in a single account. To merge your accounts visit the MergeAccounts page.

Why was my credit card payment declined?
If a payment was declined, you wil see
. Click to reveal the reason for the decline.If the website does not tell you the problem, there is regrettably little we can do to help. For security reasons, banks will not answer questions from anyone other than the account holder. If you cannot get the payment to go through, we recommend either you contact your issuing bank, or use a different card.
We only accept Amex, MasterCard, Visa.
If you are using an institutional or government credit card you may need to contact the responsible department to pre-authorize your charge. In previous years some registrants have run into problems with cards that are restricted to a very limited set of merchants or require advance notice on transactions over a certain amount.

Exhibitor FAQ’s
Q: How do I access the Exhibitor Portal?
A: Please click on the Green button with your company name. See image below:
Q: How do I get an invoice for payment?
A: Click on “Send Invoice” in the exhibitor portal. Verify the information, including the PO number is correct (if applicable). Then click the button to email to yourself. If your company requires the invoice to come from the conference, please notify us immediately.
Q: What happens if the invoice information is incorrect?
A: The invoice is auto-generated from the information you’ve entered in the “your information” section of the application. If you need name changes, a PO number added, etc., please update your information section, refresh the page, click on the “Send Invoice” tab, and send to yourself.
Q: How can other members of my team gain access to the exhibitor portal?
A: They must create a profile on the website first. Then you can add them to the exhibitor badge section, click save. They will notice the same green tab on their homepage that is shown on the first Q/A on this sheet.
Q: How do I get access to the attendee list?
A: You will not have access to the Opt-In attendee list until we have received a signed contract and payment from your company. Once we have these items, you will see a BLUE “Recruitment Information” tab in the exhibitor portal. Once you click that, a window pops up where you can download an Excel sheet and a Zip folder of CV’s for your recruitment efforts. See image below
Q: Does the conference have a lead scanning system?
A: Yes! This is built into the exhibitor portal and you will have access once the signed contract is submitted and we have received payment. Until then, please review our Wiki page with specific instructions on how it works. No app or scanning device required.
Q: Who gets access to lead scanning?
A: Only the team members who have been entered into the exhibitor badge section of the portal will have access. If someone from your team needs a full conference registration but also wants access to lead scanning then you may add them to both sections.
Q: What if my company needs additional exhibitor badges or full conference registrations?
A: The conference does not sell additional exhibitor badges. Your company will need to purchase any type of registration (usually the cheapest) to gain access to the exhibit hall. If your company needs additional full conference registrations then those will need to be purchased at the company’s expense.
Q: How come my logo won’t upload in the portal?
A: The only file accepted is an svg file. Be sure you are using the correct format. If the file you are uploading isn’t an svg file, please work with your team to create one.
Q: Is the Certificate of Insurance (COI) required?
A: Yes! Even if you have an exhibitor appointed contractor (EAC). The COI we are asking for is liability insurance for your employees who will be working the booth at the conference venue, which is not the same as the COI for an EAC. Be sure to upload before the deadline.
Q: Can my company get a breakdown of attendee demographics?
A: The conference has strict privacy policies, so we do not share that information with exhibitors.
Q: How do I fill out the exhibitor application with the correct information?
A: Please see the image below with helpful tips.
Please see the image below that you may also find helpful in navigating the exhibitor portal.
